LIQUID-MEASURING APPARATUS.

Application filed September 15, 1914.

To all whom may concern:

lie it known that we, JAMES A. MACKEN- Zn. and (inonor. V. lilAcKrnvzin, Jrd citizens of the United States residing at Ben ."vvon. in the county of Allegheny and State of Pennsylvania. have invented certain new and useful Improvements in Liquid-Measurine Apparatus, of which the following is a specification.

()ur invention relates to improvements in means for delivering liquids. preferably in measured quantities, from a superimposed measuring or secondary tank connected with a main reservoir. provided with means for etiecting the flow thereinto from the main reservoir, means for measuring the amount to be charged into the secondary tank, means f or delivering the fluid from the temporary tank in such measured amounts, and various other features of improvement. as shall be more fully hereinafter set forth.

The invention, in general, is similar to that constituting .the subject matter of another companion application filed Sept. Lil, 1914,

Serial No. 8(i'l.547.

5. A relief pipe 6 for admitting atmospheric air is connected with the upper portion of the tank 2 and may extend to any suitable point thereabov e.

The secondary or measuring tank 7, which may be of any suit-able construction, is located at any desired elevation above the primary tank for delivering through a pipe Said pipe as shown in Figs. 1 and 3, is continuous from tank 2 upwardly to the bottom of the tank 7 for direct upward flow of the liquid thcreinto through three-way valve thriving a lateral connection 10 for a delivery hose or other conduit 11. Threeway Valve 9, when. in the position shown in Fig. 5. is arranged for direct'upward flow from main reservoir 2. by manipulation of a handle 12. When in the position shown in Fig. (3. 1t arranged for flow of the liquid by gravity from tank 7 through lat-.

cral connection 10 and hose 11 to the point of consumption or use. as will be readily undcrstmul. Tank 7 provided atone side with an indicating glass 13, whereby the height of thc fluid may be seen. and suitable marks. as shown. showing the "capacity, may he placed on the tank or otherwise adjacent to the indicating gage, if desired, for showing the height of the liquid within tank 7.

For the purpose of eating a. partial vacuum in tank 7. any suitable air-exhaustin; means may be employed. but We prefer to use a siphon or injector 14- of suitable construction connected with any source of fluid pressure. as by pipe 15 having a suitable controlling valve 16 connected to an ordinary water supply main or system. and having a waste pipe. 17 leading to a sewer or suitable point of discharge. A suction pipe 18 connected with the upper end of tank 7. preferably by an upper extension '19. which may, if desired. extend to a sulfiby its lower portion 26,

tive position by means of a lock-controlled veeper or clamp 23, as indicated in Fig. 1.

rom the foregoing description it will be seon that when air is exhausted from the interior of tank 7, liquid will rise from main reservoir 2 through pipe 8 and fill the tank 7 more or less.

For the purpose of providing means for controlling the filling of the secondary tank to any desired or predetermined capacity. we have provided the mechanism illustrated in detail in Fig. 2 of the drawings. A float 2% within the tank freely rises and falls therein upon the surface of the contained liquid. Float 24 is provided with a central opening through which passes the stem 25, which,

constitutes a tubular conduit for the liquid which passes upwardly into pipe 8. Conduit 26 is provided at itslower end with a suitable packing 27 and a valve seat 28 for a vertically movable valve Said valve 29 is carried at the lower end of stem 30, which passes up- Wardly through conduit 26, and is connected with the float 24 at its upper end. Such connection is by any suitable means. as by a cross pin 31 bearing upon a supporting plate 32 surrounding the central opening in the float, and the pin is prevented against up- Ward movement above .the float by a housing plate 33. Conduit 26, as shown. is slotted at 34 longitudinally at each side, so that the conduit will thus deliver its contents upwardly into the interior of tank 7 atany position, at the same time providing clearance for pin 31 at varying positions. It will thus be seen that. conduit 26 being set at any particular position. its "alve seat 28 will be located in a corresponding position upwardly above the valve 29, when float 24 is resting upon the bottom of the empty secondary tank 7. For the purpose of so locating the conduit .26 and valve seat 28 upwardly above valve 29. so that the rise of the float and valve will close further upward flow of the liquid into the tank at a predetermined point, means are provided for raising the conduit 26 to any desired position within the control and accurate limitation of the operator. pose, conduit 26 extends upwardly through the float 24, as stated, and is provided thereabove with a series of rack teeth 35 adapted to extend upwardly through the air-exhausting pipe 19, connected with suction pipe 19, as shown in Fig. 2. Rack 35 extends between any suitable guiding means, as rollers 36, and for the purpose of actuating the rack, we provide a pinion 37 on the inner end of shaft 38 carried in any suitable bearings Shaft 83 extends ou wardly through the front of the casing 7 and a packed bearing 3 thereon, and pro vided at its outer end with a pinion 40. An actuating pinion llmeshes tliereinto, be-

For this pur resulting corresponding movement of the, connected parts will correspond to a unit of Rt measurement of the liquid, or any desired multiple thereof. For the purpose of def initely determining such unitary /amount, the movement of shaft-"42 is indicated visibly upon the front of the casing 7 by a dial 4% having secured around itd periphery projecting buttons or abutmentsj 45. These abutments are preferably made adjustable annularly, as by mounting them in slo'ts' lG so as to definitely locate each abutment in;the exact position for engagement with a limiting abutment on the shaft-actuating handle. oiiperating therewith is a pin 47 mounted within an extended visibly through suitable openings in the front of dial plate 44 the number of units as successively measured. Inasmuch as such indicating mechanism is of well known construction and use, no detailed description of it is necessary.

he operation of the readily understood from the foregoing description.

Upon any desired amount of liquid being required, the crank handle 49 will be turned to the corresponding position as to engage ment by its stem -li'. for instance. with abutment 5. indicating five gallons. This operation will elevate the valve seat i to a position above the lowermost normal position of valve 99, as suspended from the float 94 when at its lowest position. The crank handle l2 of'valve l is thrown to open position. as in Fig. 3. giving ree circulation upwardly through conduit voirQ. Valve handle 22 is then turned to open valve 16. admitting water supply to injector l4. effectingexhaust of air from the interior of casing 7. and a resulting upward new of the liquid through conduit 8. 'lhercupon float 24 will be carried upwardly upon the. surface of the liquid. carrying with it vaivo a certain extent, shaft 7e casing 48 on handle 49 of shaft 42. whereby the inner end of stem apparatus will be from main reser stem 30 and valve 29, until said val e seats against seat ZS, arresting; further upward flow into the supplemental sank '4', the amount therein uorresp inling to the desired amount of live ,Qjallons. regulated by the eapaeity oi' the tank 1' and the degree or elevation of the ('Uilv'ltlii' i as controlled lay the gearing. 'lhort-upon val e $3 beingturned to the position shown in Fig ii, the measured contents of tank 7 are delivered outwardly through lateral conduit 10 by gravity, eniptying the tank. ll; will be understood al: o that when the tank is filled to the desired extent, the Yneuuni prw during operation may be diseontinuml by closing valve ll) by its handle 22. If it l desired to empty tank T back into main ll??? ervcir this may be readily aveoinplhdied by merely turning valve 9 to the position ol' Fig. 5. The tank 7 wy also be emptied by slightly elevating conduit in until it eii'eets unseating of valve 19 against wat '28. where upon the contents will flow baekwardly into the tan ii.

In Figs. 8 and 9 we have shown a modi fied actuating mechanism for the conduit 2*) in which the pinion 3'7 is mounted upon the Shaft 38 rotatably mounted in the upper end of a casing 11, and eariying a sprocket wheel 40'. The lower end of the casing 42 is prov? al with a similar shaft 42' earrying the sprocket 41. said sprockets living (fOXlTlQLtQfl b: a (Ont/MINORS chain Shall 4-2 is provided with an operatiin haodlv veil) and a terminal button by \vhieh the sprocket gearing may be actuated. and chain 52 is provided with a fixedly attai-hed atop Said stop is (-onnovte'l vri 1 the (bulb through a vortiral rlearance \lot 51-1. and is provided with an arresting: And 5).? mounted in a: suitable easing 5(7- of the slop 5 Azi'ranged vertically of the owing and parallel ith the slot 54. is a guiding slot 5? traversed by the inner nd of stem 5:"), and at predetermined inm-vala eori-e pond ing to uhut'menta 5, are, a series of sorlflzts 45'. into which the inner end ot' stud 51' may be inserted, for fixedly holding lue chain and sprocket wheel 40' in the ueairwl po, tion. ln this .rospeet the degree of rotation of shaft 2% and the resul If elevation oi the rack bar and thecoudu; is :uwu-"atly determined.

It will be understood that. the sev ral sockets 45' are spaced apart. at predetn mined locations, corresponding to lho spatial lmations of the abutments 45. and that ear-h socket may be in the face of a plate .38 held by serew 59, by which means it may be aerarately adjusted to the exact position desired,
